P3R-620, nicknamed Tinkerbelle by some members of the Tau'ri, was a planet in the Milky Way galaxy which held a Stargate. SG-9 visited the planet in the early years of the Stargate Program, who discovered that there had been recent Goa'uld or Jaffa activity on the planet, but Stargate Command weren't sure if they would be coming back.
